Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, specifically a plastic upper and lower mold splicing device. Background Technology

[0002] During plastic production, two sets of plastic parts need to be welded together using a welding device. To ensure the neatness of the weld, the two sets of plastic parts need to be joined together by an upper and lower mold splicing device.

[0003] A device for splicing upper and lower molds for plastic welding, disclosed in CN109774166B, includes a housing, a fixing mechanism, and a storage mechanism. The fixing mechanism includes an upper mold fixing mechanism and a lower mold fixing mechanism. The inner side of the upper mold fixing mechanism is evenly provided with a plurality of first sliding grooves. A first slider is slidably installed inside the first sliding groove. An iron block is fixedly installed at one end of the first slider inside the first sliding groove. An electromagnet is fixedly installed at the bottom of the first sliding groove. The electromagnet is fixedly connected to the iron block through a first spring. Two claws are hinged to the other end of the first slider. The two claws are fixedly connected through a second spring.

[0004] The aforementioned document not only makes it very convenient to fix the upper and lower plastic molds, but also facilitates the removal of the plastic after welding. However, the aforementioned document fixes the plastic parts with clamps, which prevents the plastic parts from rotating flexibly after fixing, resulting in poor performance. Therefore, we propose a plastic upper and lower mold splicing device to solve the problems mentioned above. Utility Model Content

[0013] Preferably, the rotating lead screw and the movable block are connected by a threaded connection, and the lower part of the movable block is connected to the sliding groove on the surface of the rotating disk by a sliding block to form a snap-fit ​​sliding connection.

[0014] By adopting the above technical solution, the rotating screw can be rotated to make the rotating screw and the movable block move in a threaded manner, which facilitates the movement of the movable block inward, so as to extrude and position the plastic part.

[0015] Preferably, a spring is fixed in the inner groove of the outer protective frame, and a limit block is fixed to the end of the spring.

[0016] By adopting the above technical solution, the use of springs inside the outer protective frame allows the limiting block to bounce within the inner groove of the outer protective frame.

[0017] Preferably, the limiting block at the inner end of the outer protective frame and the toothed block on the surface of the rotating disk form an engaging connection.

[0018] The above technical solution facilitates the engagement of the limiting block with the toothed block on the surface of the rotating disk, so as to position the rotating disk after it rotates.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please refer to Figures 1-5. This utility model provides a technical solution: a plastic upper and lower mold splicing device, including a side plate 1 and a rotating handle 11. A first conveying assembly 2 is installed at the right end of the side plate 1. The first conveying assembly 2 includes a first active toothed roller 201, which is rotatably connected to the middle of the side plate 1. A first driven toothed roller 202 is rotatably connected to the end of the side plate 1. A first conveying toothed belt 203 is meshed with the surfaces of the first active toothed roller 201 and the first driven toothed roller 202. A second conveying assembly 3 is installed at the left end of the side plate 1. The second conveying assembly 3 includes a second active toothed roller 301, which is rotatably connected to the side of the side plate 1 near the first active toothed roller 201. A second driven toothed roller 302 is rotatably connected to the other side of the side plate 1. A second conveying toothed belt 303 is meshed with the surfaces of the first active toothed roller 201 and the second driven toothed roller 302. A servo motor 304 is fixedly connected to the end of the first active toothed roller 201 on the surface of the first active toothed roller 201 and the second active toothed roller 301. Rotating gears 18 that mesh with each other are fixed on the outer ends of the side plate 1. The conveying directions of the first conveying component 2 and the second conveying component 3 are opposite. When the second active toothed roller 301 is driven to rotate by the servo motor 304, the rotating gears 18 at the end of the first active toothed roller 201 mesh with each other, so that the two sets of conveying components can convey synchronously towards each other, so as to facilitate the docking of plastic parts.

[0030] Please refer to Figures 1-5. A rotating shaft 4 is fixed above both the first conveying assembly 2 and the second conveying assembly 3. A rotating disk 5 is connected above the rotating shaft 4. The rotating disk 5 is connected to the rotating shaft 4 via a bearing connection, allowing the rotating disk 5 to rotate easily on the rotating shaft 4 on the upper surface of the conveyor belt, facilitating the adjustment of the welding position of the plastic parts. A fixing block 6 is fixed to one side of the upper part of the rotating disk 5, and a rotating screw 7 is rotatably connected to the end of the fixing block 6. A movable block 9 is connected to the surface of the rotating screw 7. Rubber pads 10 are bonded to the inner surfaces of the fixing block 6 and the movable block 9, protecting the plastic parts during fixing. A groove 8 is formed on the middle surface of the rotating disk 5. The rotating screw 7 is connected to the movable block 9 via a threaded connection. The lower part of the movable block 9 is connected to the groove 8 on the surface of the rotating disk 5 via a sliding block 17, forming a snap-fit ​​sliding connection. Rotating the rotating screw 7 allows the rotating screw 7 to rotate. The movable block 9 moves in a threaded manner, which facilitates the inward movement of the movable block 9 for the extrusion and positioning of the plastic part;

[0031] Please refer to Figures 1-5. A sliding block 17 is fixed below the movable block 9. A rotating handle 11 is fixed to one side of the upper surface of the rotating disk 5. Tooth blocks 16 are evenly fixed to the lower surface of the rotating disk 5. An outer protective frame 12 is provided on the outer side of the rotating disk 5 and fixed to the upper surface of the first conveying toothed belt 203 and the second conveying toothed belt 303. A spring 14 is fixed in the inner groove 13 inside the outer protective frame 12. A limit block 15 is fixed to the end of the spring 14. The limit block 15 can bounce in the inner groove 13 inside the outer protective frame 12 by using the spring 14 inside the outer protective frame 12. An inner groove 13 is provided on one side of the outer protective frame 12. The limit block 15 at the inner end of the outer protective frame 12 and the tooth blocks 16 on the surface of the rotating disk 5 form a locking connection, so that the limit block 15 and the tooth blocks 16 on the surface of the rotating disk 5 can mesh with each other to position the rotating disk 5 after rotation.

[0032] Working principle: First, during use, the welded plastic parts are placed above the rotating disk 5. By rotating the lead screw 7, the lead screw 7 and the movable block 9 move threadedly, so that the sliding block 17 on the surface of the movable block 9 engages and slides on the sliding groove 8 on the upper surface of the rotating disk 5. This allows the movable block 9 to cooperate with the fixing block 6 to position the plastic parts. After fixing the two sets of plastic parts, the servo motor 304 on the second conveying assembly 3 is turned on, causing the servo motor 304 to drive the second active toothed roller 301 to rotate. This causes the second active toothed roller 301 and the second driven toothed roller 302 to engage with the second conveying toothed belt 303. The rear end of the second active toothed roller 301 and the rear end of the first active toothed roller 201 on the first conveying assembly 2 are both fixed with meshing rotating gears 18, so that the first conveying assembly 2 and the second conveying assembly 3 can move towards each other, facilitating the docking of the plastic parts above the rotating disk 5. When fixing the plastic parts, the rotating disk 5 can be rotated. The surface rotating handle 11 causes the rotating disk 5 to rotate inside the outer protective frame 12, so as to adjust the welding position of the plastic part above the rotating disk 5. The outer protective frame 12 is equipped with a spring 14 and a limiting block 15, which can be used to lock the toothed block 16 on the surface of the rotating disk 5 by the limiting block 15, so as to position the rotating disk 5 after rotation. This is the working principle of the plastic upper and lower mold splicing device.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
